General Plan

The plan is to figure out if cheap nail polish last long more than expensive nail polish. Painting every other finger nail of 10 test subjects with expensive nail polish and the other finger nails with cheap nail polish. In order to keep track of which is expensive and which is cheap they will be different colors. After that is taking pictures of the nails every other day, also every other day, measuring each nail to figure how much the nail polish has lasted longer. The experiment is being done at school in the science classroom.

Background Research

Cheaper nail polish does last longer because the people who make expensive nail polish just want look like its worth a lot of money. Some expensive brands of nail polish are expensive for a reason because they have some expensive ingredients in it, but it doesn’t mean it will last longer than cheap nail polish.The expensive nail polish seems to last longer than cheap nail polish but it also depends on the brand itself.
It depends on the brand most of the time like what they put into it and stuff but I've been to numerous websites, and one person did a comparison with the brands Barry M the cheap nail polish and O.P.I. the expensive nail polish. The person applied the nail polish on a Monday and started with the brand Barry M. By Wednesday it had minor cracks, on Thursday it was peeling and it all came off. She applied some on her toes the Saturday before and she had it on for two weeks before minor cracks showed. She applied O.P.I on a Monday and it had Small chips by Thursday. Her conclusion was that it was worth buying expensive nail polish then cheap nail polish.
Another person did another nail polish cheap vs expensive nail polish. She came up with yes, it is worth buying expensive nail polish, but beware of certain types of expensive brands for they can be cheating you of your money.
Cheap brands are good too, but be careful of buying of buying off-name brands for they say that type nail polish might be not good for your nails. One way to see if you are getting really good cheap nail polish is by checking the ingredients on it and it is best to avoid the ones that have fragrance in them because they are not good for sensitive skin. Some ways to warn you if you are buying really bad cheap nail polish is to look on the label to see if it has been worn, a sign of age and settling of color at the bottom of it, is that it has been on the shelf for a long time.

One picture of each person's fingernails on day one (10 pictures)
One picture of each person's fingernails on day seven (10 pictures)

Discussion

The question was “does cheap nail polish last longer than expensive and does it chip more?” The question was answered, and the answer was very clear that cheap nail polish does chip more, and it doesn’t last longer than expensive. The evidence was on the trials fingers, that is how the answer was discovered. The finger nails proved the answer to be correct.
The hypothesis was supported by the results, the hypothesis was the answer. It was hypothesized that the cheap nail polish would not last longer than the expensive and it would definitely chip more. And the hypothesis turned out to be true.
The patterns that could be identified within the data and observations, it was found consistently that the expensive nail polish would always chip less than cheaper nail polish. We used several brands which was the independent variable and the dependent variable is how much chipped off which was constantly changing over the days
During this experiment there was a couple challenges one of the ones we could not have controlled was that two of the girls scratch off their nail polish and therefore had to delete the data collected from them. We could have improved this project by asking what the test subjects did during their day that cause chipping different people have different things they do so it could chip faster or slower but it didn’t matter what type of nail polish.
The information that was used mostly came from beauty websites giving opinions about which is the best nail polish to be used, some of the suggested were used in this experiment. The only technology that was used during this experiment was a digital camera to take pictures of the test subject’s nails and a computer to put down the data. The results that we gather will help people with the same question by the brands of nail polish used in this experiment so the person will know how much chipped off with that brand.
The knowledge gained from this experiment could be of use to anyone. Anyone who wears nail polish and is looking for a great nail polish to use that will not chip. The problems that is might help solve would be, the use of nail polish. The results would help many people choose the best type of nail polish. Mostly teenage girls, but also adults, and children. The new breakthroughs in information would be, which brand would be better so that they would not waste production on other nail polish brands and just use the several brands that will last the longest and is better for your nails.
